Abstract (en)
A light guide plate and a backlighting device including the light guide plate are disclosed. The light guide plate may include a substrate configured to propagate a first light beam or a second light beam inside the substrate based on an effect of total internal reflection, a prismatic pattern configured to couple the first light beam out of the substrate in a three-dimensional (3D) display mode, and a linear pattern configured to couple the second light beam out of the substrate in a two-dimensional (2D) display mode.
